Astrology and astronomy were archaically treated together (Latin: astrologia), but gradually distinguished through the Late Middle Ages [1] into the Age of Reason. Developments in 17th century philosophy resulted in astrology and astronomy operating as independent pursuits by the 18th century.

A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.
The use of astronomical symbols for the Sun and Moon dates to antiquity. The forms of the symbols that appear in the original papyrus texts of Greek horoscopes are a circle with one ray for the Sun and a crescent for the Moon. [3] The modern Sun symbol, a circle with a dot (☉), first appeared in Europe in the Renaissance. [3]
[3] The success of astronomy, compared to other sciences, was achieved because of several reasons. Astronomy was the first science to have a mathematical foundation and have sophisticated procedures such as using armillary spheres and quadrants. This provided a solid base for collecting and verifying data.
A diagram of observed minus calculated values over time, showing how observed data differ from theoretical values which have been calculated according to a particular scientific model. It is often used as a diagnostic tool to determine the accuracy of the model. With a variable star, it is typically used to compare phase differences over time. [25]
[10] [12] The influence of the stars was in turn divided into natural astrology, with for example effects on tides and the growth of plants, and judicial astrology, with supposedly predictable effects on people. [13] [14] The fourteenth century skeptic Nicole Oresme however included astronomy as a part of astrology in his Livre de divinacions. [15]
On the other hand, some of the material could be fit in the history of astrology, to perhaps replace the statement: "Isidore of Seville (d. 636) was one of the first to distinguish between astronomy and astrology." The distinction was made by many before this time as I have shown in the revised intro to astronomy/astrology.
